Traditional Zonal Lighting and Controls Wiring
• 3 separate systems for
power, control and
measurement
• Significant design time
and field set up
• Limited control – zone-
per-room
• Limited Intelligence
• Not easily expanded,
upgraded or re-
provisioned

Zonal vs GranularFeature Area
Zonal Granular Difference
Daylight Limited Area All Areas No sacrifice of savings for first cost
Occupancy Large Area Fine Grain Control Doesn’t activate entire area for one user
Facility Utilization
Limited/No Data
Complete Provides needed information for planning and operations
User Control
Not Possible Fixture by fixture PC, user friendly, password level
Security Limited Data, Low Resolution
Every 10 Feet (3m)
In Development
Traffic Flow Limited Data, Low Resolution
Every 10 Feet (3m)
Adjustable time base allows pattern Recognition
HVAC Integration
Additional Equipment
Fine Grain High Density
Usable data for facility manager and BMS via BACnet
Intelligence Network Dependent
Localized control and response
Walk-thru logic for hallways, Soft edges in offices (Envelope)
